I know a couple of comments have mentioned this already, but this apparently grows out of him being in a pickle financially at the moment and resenting the time he has put into doing free work:

I've done lots of nice things for people over the years for free. A lot of the things I'm good at are inherently hard to monetize (most moderating positions are unpaid, for example).
I was homeless for years. I still write about homelessness and try to provide other forms of support for people who are homeless or at risk of homelessness.
Some of the things that would help:
1. Universal health care coverage in the US. ("free"/provided by the government)
2. Fix our housing policy issues such that more small housing in walkable neighborhoods becomes available.
If those two things were done, a single adult could potentially support themselves on part-time minimum wage work while renting a single room until they get back on their feet. That's currently not feasible.
I am not against open source. (I just submitted my first pull request to open source a few hours ago.) But I do recognize that there are systemic issues and we need to make it easier for people to make their lives work so they don't wind up all pissed off over what they have done for free when something goes sideways.
